[1] It is south of Lady Evelyn-Smoothwater Provincial Park and west of Lake Temagami, within Sudbury District.

It flows from Obabika Lake in a south-westerly direction and drains into the Sturgeon River.

The lower Obabika River is rather wide with several oxbow ponds, and obstructed by occasional log jams.

Although the current is strong, the only noteworthy rapids occur immediately before its confluence with the Sturgeon River.

It is part of the traditional indigenous travel network called "nastawgan", which has changed little over many centuries.
